Heartburn is a burning sensation in the chest, often rising from the stomach, typically after eating. It's caused by stomach contents flowing back into the food pipe. Common triggers can include certain foods (like spicy or fatty meals, citrus), caffeine, alcohol, large meals, or lying down soon after eating. A healthcare provider might ask about the timing, frequency, and severity of your symptoms, and if anything makes it better or worse. Keeping a food and symptom diary can help pinpoint personal triggers. Seek urgent care if you experience severe chest pain, especially with shortness of breath, sweating, or pain radiating to the arm or jaw, as these can indicate other serious conditions.
